Abstract
A tag disclosed in this invention detects theft of bills, notes, or securities positioned therewith in a cash register, a safe, or the like. The capability of a tag-detecting sensor is not affected by a conductive or magnetic auxiliary member disposed between the sensor and the tag. The tag for detecting theft, which has one or more resonant circuit sections on an insulating base sheet, is positioned with an article in a specified place. An alarm is not activated when the tag is detected by the sensor, while it is activated when the tag is not detected by the sensor. At least one of the resonant circuit sections is disposed apart from the conductive or magnetic auxiliary member, with respect to the auxiliary member to be disposed between the sensor and the tag. The specified place refers to a case positioned in a cash register or a safe; the article includes bills, notes, or securities; and the auxiliary member is a metal retainer. A fold line is formed on the insulating base sheet, and the resonator circuit sections are arranged apart from the fold line on the sheet.
